Nab-Paclitaxel til behandling af ældre patienter med lokalt avanceret eller metastatisk brystkræft

16. oktober 2026 opdateret af: City of Hope Medical Center

Effekt og tolerabilitet af nanopartikelalbumin bundet paclitaxel (Abraxane) hos patienter 65 og ældre med lokalt avanceret eller metastatisk brystkræft

This phase II trial studies the side effects of nab-paclitaxel in treating older patients with breast cancer that has spread from where it started to nearby tissue or lymph nodes (locally advanced) or to other places in the body (metastatic). Drugs used in chemotherapy, such as nab-paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

Detaljeret beskrivelse

PRIMARY OBJECTIVE:

I. To evaluate the tolerability (grade 2-5 toxicity, neuropathy grade 2 or higher, need for dose reductions, or delays) of weekly nab-paclitaxel in older adults with locally advanced or metastatic breast cancer.

SECONDARY OBJECTIVES:

I. To evaluate the efficacy (response and time to progression) of weekly nab-paclitaxel in older adults with locally advanced or metastatic breast cancer using a stratification factor based on patient age (at least 5 patients age 75 years or older and no more than 15 patients age 65-70 years).

II. To explore predictors of the need for dose reduction, dose delays, or grade 2-5 toxicity and neuropathy grade 2 or higher based on a cancer-specific geriatric assessment.

OUTLINE:

Patients receive nab-paclitaxel intravenously (IV) over 30 minutes on days 1, 8, and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.

Tidsramme
Response Determined by Response Evaluation Criteria in Solid Tumors
Tidsramme: Up to 2.5 years

Rates and associated 95% exact Clopper and Pearson binomial confidence limits will be estimated for objective response rate (complete response [CR] + partial response [PR]).

RECIST:

Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes must have reduction in short axis to <10 mm

Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters

Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. Additionally, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered progression

Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study
Up to 2.5 years
Median Progression Free Survival (PFS)
Tidsramme: From the date treatment begins until the first date on which recurrence, progression, or death due to any cause, assessed for about 1.5 years

PFS will be estimated using the product limit method of Kaplan and Meier.
From the date treatment begins until the first date on which recurrence, progression, or death due to any cause, assessed for about 1.5 years
Cancer-specific Geriatric (CARG) Assessment
Tidsramme: CARG measured prior to treatment, toxicities and dose reduction measured up to 30 months

General linear models and descriptive methods will be used to explore factors as identified by a CARG assessment that may be predictive of toxicity (grade 3 or higher adverse events) or dose reduction.

The cancer specific geriatric assessment score includes an evaluation of functional status, co-morbidity, cognition, psychological stats, social functioning and support, and nutritional status. It assesses a patient's age, gender, height, weight, cancer type, dosage, number of chemotherapy agents, hemoglobin, hearing, number of falls in past 6 months, able to take own medicine, whether walking is limited, have physical or emotional problems interfered with social activities and serum creatinine.

Scores can range from 0 to to 1, with a higher score indicating higher risk of chemotherapy toxicity. Scores from 0 to 5 are considered low risk, 6 to 9 are considered intermediate risk, and 10 to 19 are considered high risk.
